To prepare 2-chloro-6- (trifluoromethyl) pyridine-3-formamide, the following method is often followed.
Take 2-chloro-6- (trifluoromethyl) niacin as the starting material, and heat it with thionyl chloride. The carboxyl group of niacin is converted to the catenyl chloride group to obtain 2-chloro-6- (trifluoromethyl) niacin chloride. This step is violent and needs to be carried out in a well-ventilated place with controlled temperature, because hydrogen chloride and sulfur dioxide escape. The reaction formula is: 2 -chloro-6- (trifluoromethyl) niacin + SOCl ² → 2 -chloro-6- (trifluoromethyl) niacin chloride + HCl ↑ + SO ³ ↑.
times, dissolve the prepared niacin chloride into a suitable solvent, such as dichloromethane, and slowly add concentrated ammonia or ammonia gas at low temperature. The acid chloride group of niacin chloride reacts with ammonia, and the chlorine is replaced by an amino group to produce the target product 2-chloro-6- (trifluoromethyl) pyridine-3-formamide. In this step, the temperature should be controlled at 0-5 ° C to avoid side reactions. The reaction formula is: 2-chloro-6- (trifluoromethyl) nicotinyl chloride + NH 🥰 → 2-chloro-6- (trifluoromethyl) pyridine-3-formamide + HCl.
